UNIQLO Kids Sweatpants 110cm Gray These were mainly worn indoors, but I fell while wearing them outside, and there are light brown stains on both knees. (They might come out with bleach, etc., but I only use natural detergents, so the stains didn't come out.) - Brand: UNIQLO - Size: 110cm - Color: Gray These have been stored at home. Please understand that these are used items before purchasing. Thank you for looking.
